Specification of Letters Patent.

Patented Dec. 26, 1916.

To all whom it may concern:

Be it known that I, EDMUND NOLAN, a citizen of the United States, and aresident of Detroit, in the county of Wayne and State of Michigan, haveinvented a certain new and useful Grease-Cup Cap, of which the followingis a specification.

This invention relates to grease cups and has for its object aparticularly simple, efficient, and durable construction by which amember of the ratcheting mechanism of the cup is secured to the cap; andthe invention consists in the novel features of construction hereinafterset forth and claimed.

In describing this invention, reference is had to the accompanyingdrawings, in which like characters designate corresponding parts in allthe views.

Figure 1 is an elevation of this cap. Fig. 2 is a longitudinal sectionalview on line 2-2, Fig. 1. Fig. 3 is an inner face view looking upwardlyin Fig. 1. Figs. 4: and 5 are elevations of the rod which is one of themembers of the ratcheting mechanism of the cup.

This invention comprises, generally, a grease cup cap having a portionor member thereof formed with opposing or double walls, and a memberhaving a portion inserted between said opposing walls, the walls beingcompressed upon said member, and the member being embedded in said wallsby the compressing of the walls.

1 designates the cap of the grease cup, the cap being here shown asformed of sheet metal and having a top which has a double walled wing 2compressed therefrom, this wing extending diametrically across the topand the space or crevice between the walls thereof opening into theinterior of the cap. The cap is also formed with internal threads forturning on the base of the cup.

3 is a member forming part of the ratchet mechanism of the cup, thismember being here shown as a rod having a head 4c extending between thewalls of the wing. The head 4L is flattened and widened with respect tothe rest of the rod, so that two shoulders 5 are provided at the base ofthe head, which shoulders engage the inner face of the top, and the headis usually roughened or knurled.

After the cap has been formed with a hollow walled wing, the head 4 oftherod is inserted between the walls of the wing and said wallscompressed upon the knurled head thereof for securing the rod to thehead. The rod is non-circular, or square and is designed to coact with asuitable spring device which engages the sides thereof, said devicebeing secured at the base of the grease cup and engaging the squaresides of the rods so as to resist rotation of the rod, as will beunderstood by those skilled in the art.

W hat I claim is:

1. A grease cup cap formed with a mem-' ber located on the top thereofand having opposing walls, the space between which opens into theinterior of the cap, and a rod extending lengthwise of the interior ofthe cap and having a portion extending between the opposing walls ofsaid member, the walls being compressed upon the rod, substantially asand for the purpose set forth.
